cylinder wherein is disposed the material to be cleaned, and the primary object of the invention 5 is to provide such a device which permits intro duction and removal of cleaning fluids without stopping the rotation of the cylinder, the said objects being fulfilled by special construction more fully hereinafter described and claimed. A still further object of this invention is the provision of a washing machine that is cheap to construct, simple in operation, strong and durable, and includes a drying attachment and water heater that combines with the specially constructed cylinder in a manner to present a desirable piece of equipment.

A primary aim of this invention is to provide in a washing machine, a specially designed cylinder that is divided to present a majorand a secondary compartment, separated from each other by a perforated partition, said secondary compartment being of greater diameter than the major compartment for the purpose hereinafter specified.

This application is a continuation-impart of uary 4, 1932, and relating to improvements in Washing machine, which application is now abandoned and contains part of the subject matter of this application.

One embodiment of the invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a broken side elevation of a washing machine made in accordance with this invention.

Fig. 2 is a top plan view of the same, and,

Fig. 3 is a vertical, central cross section through the cylinder of the machine. I

A washing machine embodying this invention 40 should be made of some suitable rust-proof material and should have a combined housing and support structure 6 that includes two opposed standards 8, upon which is rotatably mounted cylinder 10 which forms a major compartment 12 and a secondary compartment 14.

A transverse partition 16 having a large number of perforations 18 therethrough forms the medium of separating major compartment and secondary compartment 12 and 14 respectively. As indicated in the drawing, secondary compartment 14 is of greater diameter than major compartment 12. As a matter of fact, it overlaps or extends beyond the wall of cylinder 10 which forms major compartment 12. An opening 20, having an inwardly directed flange 22 is formed 1934, Serial No. 705,734

at the axis of cylinder 10 and through one outside wall 24 thereof, so that a stub shaft 26 that is rigidly secured to partition 16 may be projected outwardly from secondary compartment 14 through opening 20 to standard 8, which rotatably supports the said shaft 26. Opening 20 is appreciably larger than the diameter of stub shaft 26 and at least sufiiciently large enough in diameter to permit pipe 28 to enter secondary compartment 14 and terminate at the lowermost portion thereof.

Pipe 28 extends out through standard 8 to a source of water supply and a drain branch 30 extends downwardly into housing 32 to any suitable pump which may be brought into play when it is desired to pump water from within cylinder 10. Obviously, the position of the end of pipe 28 will allow removing substantially all of the water from the two compartments formed in cylinder 10. As soon as the pump, not here shown, ceases to draw water from within cylinder 10, supply water may be forced into the cylinder through pipe 28. A stub shaft 34 in axial alignment and directly opposed to stub shaft 26 extends outwardly from wall 36 of cylinder 10 to be journalled in standard 8. It is through this stub shaft 34 that power to rotate cylinder 10 is applied and any means whereby such rotation may take place is sufficient to fulfill the requirements of this invention.

In the instance illustrated, a worm gear 38 may be driven through the medium of shaft 40 which extends into housing 32 below cylinder 10 where a suitable motor may be positioned to impart driving power. Clutch pedals or levers may be used to appropriately drive and release the driving means from any part of the washing machine. Cylinder 10 is supplied with an opening 42 and a door 44 is hingedly secured as at 46 to close said opening during the washing op-- eration. A latch handle 48 is supplied, and in addition to this structure, cylinder 10 has a plurality of lifts 50 on the inner annular wall thereof which tend to move the materials being washed to the upper part of the cylinder from where they are dropped during the washing operation.

A drying attachment forms a component part of this washing machine and the same is positioned adjacent rotatable cylinder 10 as shown in Figs. 1 and 2. This drying attachment comprises a spinning retort 52 that is mounted within. housing 54 and driven by shaft 56 through the medium of a drive pulley 58 which may be connected to a source of power in any suitable manner. Spinning retort 52 has perforations 60 formed through the walls and when the washed materials are placed in retort 52 through the opening 62 in the to, thereof, water is driven therefrom through said opening 60. and into housing 54, from where the same is drained off may be moved from one position to the other' Two upstanding ears '72 pivotally,

with ease. engage member 66 and through this particular construction a double purpose is performed thereby.

Obviously, housing 32 is utilized to contain all the necessary elements to properly operate'this washing machine, and a door '74 permits access to this housing.- Y

It is sometimes desirable during the washing operation to apply heat to the water, and if so, an electrical element '76 is contemplated. This encased element is positioned as shown in Fig. 1 adjacent the lowermost portion of secondary compartment 14 and maybe carried in such place by an arm 78 which projects through opening 20 to be afiixed to standard 8. Suitable electrical conductors 80 supply current to element 76 and a switch may be provided as desired.

It is obvious that a washing machine embodying the invention will utilize a minimum amount of water, and because of the hereinbefore mentioned structure, the materials being washed may be rinsed without removing them from compartment 12 for the purpose of replacing the wash water.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. In a washing machine, a rotatable cylinder; a perforated partition dividing said cylinder into a major compartment and asecondary compartment concentric therewith and overlapping the former, there being an opening formed through the wall of said cylinder forming the other side of said secondary compartment; draining means for the secondary compartment; and means for rotatably supporting said cylinder including a shaft passing through said opening and afiixed o said. partition.

2. In a washing machine, a rotatable cylinder; a perforated partition dividing said cylinder into a major compartment and a secondary compartment concentric therewith and overlapping the former, there being an opening formed through the wall of said cylinder forming the other side of said secondary compartment; means for rotatably supporting said cylinder having an element thereof passing through said opening and connected to the partition; and a drain pipe entering said secondary compartment through said OPBIllDg'.

3. A washing machine comprising a rotatable cylinder; a perforated partition dividing said cylinder into a major compartment and a secondary compartment concentric therewith, said secondary compartment having a greater diameter than the major compartment and overlapping the, same; oppositely directed axial shafts rotatably supporting said cylinder, there being an opening in one side of said cylinder, one of said shafts being attached to said partition and passing through the opening; and a drain pipe entering said secondary compartment at a point spaced from the axis of said cylinder and terminating in the lowermost portion of said secondary cylinder whereby to drain water from both compartments of said cylinder as the same is rotated.

4. In a washing machine, a rotatable cylinder; a perforated partition dividing said cylinder into a major compartment and a secondary compartment concentric therewith and overlapping the former, there being an opening formed through one wall of said cylinder forming a side of said secondary compartment; draining means for the secondary compartment; oppositely directed axial shafts rotatably supporting said cylinder, one of said shafts extending through said opening and secured to-said partition for rotation with the cylinder; and an inwardly directed flange extending around the periphery of said opening, the

opening being appreciably greater in diameter,

than the stub shaft extending therethrough.

5. In a washing machine, a rotatable cylinder; a perforated partition dividing said cylinder into a major compartment and a secondary compartment concentric therewith and. overlapping the former, there being an opening formed through one wall of said cylinder forming aside of said secondary compartment; oppositely directed axial shafts rotatably supporting .said cylinder, one of said shafts extending through said opening and secured to said partition for rotation with the cylinder, said opening being appreciably greater in diameter than the stub shaft extending therethrough whereby to create an annular opening around said shaft; and a stationary drain pipe entering said secondary compartment through said annular opening in spaced relation to the rotatable shaft.
